| Outline of Final Research Achievements |
The method to coat polystyrene (PS) with hydroxyapatite (HAp) in a simulated body fluid via a protein adsorption layer has been developed. This method can apply to coat the subjects with complex structures and various kinds of proteins were used as protein adsorption layers. The differentiation from mesenchymal stem cells to osteoblasts was promoted on HAp-coated PS compared to PS for cell culture, and differentiation into adipocytes and chondrocytes were suppressed. In the polysaccharide composite films prepared by utilizing the hot press method, adhesion and proliferation of cells depended on the type of anionic polysaccharides of the films. The influence of mechanical physical properties and signals derived from interaction between sugar of polysaccharide and cell receptor was suggested. The possibility of control of differentiation of mesenchymal stem cells depending on the type of anionic polysaccharide was expected.
